ELECTRICAL ADVERTISING ANNUNCIATOR FOR CARS.

SPECIFICATION forming part of Letters Patent No. 584,700, dated June 15, 1897.

Application filed September 29, 1896. Serial No. 607,888. (No model.)

To 66 whom it may concern.-

Be it known that we, JAMES P. ORR and GEORGE H. FUGH, citizens of theUnited States, residing at Pittsburg, in the county of Allegheny andState of Pennsylvania, have invented a new and useful ElectricalAdvertising-Annunciator for Cars, of which the following is aspecification.

Our invention relates to improvements in the running of cars; and theobjects of our invention are, first, to furnish passengers timely. andreliable information of next stop second, to afford an inducement(advertisin g space) to railway companies to adopt its use. We attainthese objects by the mechanism illustrated in the accompanying drawings,in which Figure 1 is front elevation of the entire machine. Fig. 2 is avertical section of central parts of mechanism, and Fig. 3 is adiagrammatic view illustrating the circuits in our invention.

Similar letters refer to similar parts t-h roughout the several views.

The mechanism is conveniently mounted in a suitable cabinet having aglass front, all of which is available for illuminated advertisementsexcept the part in front of F and F which will display the name of astreet or station and a business-card respectively and successively.Cylinder F is mounted longitudinally near the front of cabinet and isprovided with a number of peripheral pins or rods adapted to themounting of thin metallic plates or cards, on the one side, F of whichis attached the name of a street or station, and on the other side, F isattached a bnsinesscard. These cards, pivotally mounted on F, are heldin position and made to turn with F by the motion of belt F which isprovided with teeth spaced to correspond with the number of cards orleaves on F and is propelled by the rotation of pulley Gr. As belt Fmoves forward its teeth successively release the plates or leaves andthey swing downward from the position of F to F as shown by dottedlines, 'Fig. 2. i

In the motor the helices A and B are rigidly mounted in pairs in such amanner that the positive cores will be opposite each other, so also thenegative cores, with suflicient space between for the pivotally mountingof an any non conducting material.

electromagnetic armature to swing in the magnetic field of helices A andB.

The armature is provided with two coils with cores mounted with bothpositive ends in the same direction. Then both negatives will be in theopposite direction, (the cores not being connect-ed magnetically.) Nowit will be observed that in the magnetic field A one core is positiveand the other is negative, and the positive end of both armature-coresbeing in the same field one will be attracted and the other repelled,and as the center of motion is between the two helices of the armaturemotion will be produced and continued until positive and negative corescome in contact. Now if the current in J and J be made to flow ormolecularly rotate in the opposite direction, then the attractive corebecomes the repelling one and the repellingcore becomes the attractingone, producing motion in the opposite direction. As the phenomena in Ais coincident in B and J, they all combine to produce motion in onedirection until the current is reversed in J and J then in the oppositedirection, thus prod ucin vibratory motion, which by lever P, and linkconnecting with shaft C by crank and pin C rotary motion is produced.

0n shaft 0 a fly-wheel G a worm C to engage worm-wheel G, and acommutator O are mounted.

Oommutator O is a small pulley made of It has two peripheralcontact-plates having offset portions, but each extending entirelyaround the shaft and separated from each other by a ring of insulation,there being four contactbrushes, two of which, R and R are adapted toengage each contact-plate alternately; but both of them never engage thesame plate at the same time,while each of the other two brushes arealways in engagement with the same contact-plate, one brush for oneplate which is connected with helix J and the other brush for the otherplate which is connected with helix J The current from battery, Fig.

3, flows in the direction of arrows through brush R, commutator O,thence through helices J and J returning to opposite side of commutator,thence through R and helices A and B, returning to battery. As therotation of commutator brings the offset portion IOO of the other platein contact with brush R the current will be carried through helices Jand J 2 in the opposite direction, as shown by dotted arrows. Brushes Rand R mounted on opposite sides of commutator, come in contact withinsulators O and 0 just as crank O is in position of dead-center,breaking circuit and demagnetizin g the c0res,which will then beseparated by the momentum of fly-wheel and spring P before brush R comesin contact with the other semicircular plate, closing the circuit andtransmitting the current in the opposite direction through helices J andJ This phenomenon will be automatically repeated, propelling worm-wheelG and belt F until a tooth on belt engages dog H in circuit-breaker H,causing arm to swing free from contact-plate H, dog 11 being propelledupward, thus automatically opening the circuit at H. The circuit will beclosed by the usual bell-rope signals given by the conductor, (one pullto stop and two to start,) given at each stop or station. Ratchet-wheelH has twelve teeth and four pins to successively engage lever H causingone end to swing upward and the other end to withdraw dog 11 fromengagement with pin on F closing the circuit as arm H swings intocontact with H. Sliding pawl H is provided with a spring to engage H anda spiral spring H to propel pawl by reciprocating traction on bell-rope,with which it is connected. Pinion K is mounted to mesh with worm-wheelG and is provided with pins to engage bell-clapper K. WVorm-wheel G ismounted on shaft by a clutch permitting shaft and pulley G to be turnedrapidlyforward by crank G to adjust F when car does not make a full run.Clutch is thrown in gear by pressing knob on link connected with lever GLamp L is mounted in any convenient position in cabinet to illuminatestationary and movable advertisements.

Having thus fully described our invention, what we claim, and desire tosecure by Letters Patent, is

1. In an electrical advertising-annunciator, the combination of acylinder F having leaves or cards, a controlling-belt having teeth toengage said cards with a crank-shaft having thereon pulleys to operatesaid belt and cylinder, a worm-wheel having a clutch connection withsaid shaft and an operating-motor and motor-circuit including oneautomatic circuit-opener II, having circuit-closer H operated bybell-cord and a bell-clapper pinion K substantially as described.

2. In an electrical advertising-annunciator, the combination of acabinet comprising a glass front illuminated to display leaves F, andother advertising matter with an electric propelling-motor comprisingsix helices, four of which are mounted in pairs with space between, twohelices pivotally mounted between said pairs as an electromagneticarmature and having arms P, a crank-shaft O and a link connectionbetween said arms and said crankshaft, substantially as set forth.

3. In an electric motor the combination of an electromagnetic armaturepivotally mounted, between fixed electromagnets, having arms P, acrank-shaft 0 having thereon a fly-wheel, aworm, a commutator and a linkconnection between said arms and said crankshaft with' brushes R and Radapted to engage oftset portions of peripheral contactplates ofcommutator, and other brushes being a part of circuit connection betweensaid commutator and said electromagnetic armature, all substantially asspecified.
